1. the yellow plug is air temp sensor
2. the black plug is cold start injector
3. hose with a screw is a vacumn hose (next to yellow plug)
4. the other hose is charcoal canister line
- you need the loom with the correct plugs on it to hook up the air temp and cold start.
- the hose next to the plug should either go to the map sensor or too the fuel pressure reg......
- the other hose should go to the charcoal canister to draw fuel vapour from the tank
all these things arent required to make the car run (unless map sensor isnt pugged in)
so you can make them look like they are connected to get the RWC, but in reality they are doing f**k all
